# files and all the output is produced by a single run of docbook.
# It does not look a rocket science, but I honestly still did not
# guess right combination.
# docbook scripts are incredibly dirty in the sense that they leak
# lots of some strange temporary junk directories and files.
# So, scope it to a temporary dir and clean all after each run.
